Activation And Inhibition Of The Plasminogen/Plasmin System

Summary
Plasmin is crucial enzyme present in blood plasma that functions in clot dissolution, inflammation, tissue remodeling, and wound healing. We aim to study how this enzyme system is controlled, by studying its interaction with receptors, co-factors and inhibitors. The information we gain will help drive the development of new generation therapeutics for the fine control of plasmin function in clotting disease, bleeding and inflammation.
Interactions Between RAGE And The Type 1 Angiotensin Receptor Determine The Pro-atherosclerotic Actions Of Angiotensin II

Summary
Heart attacks and strokes are a major cause of death and disability in Australians. Activation of the renin angiotensin system plays a key role in the development and progression of atherosclerosis, the process that leads to narrowing and obstruction of arteries. In preliminary data we have found a way to block these pathways without affecting the control of blood pressure. We believe that interventions based on these data will be important for the prevention and treatment of heart disease.
Regulation Of Neural Progenitor Cell Self-renewal By The RNA-binding Protein ZFP36L1 During Development And Disease

Summary
The timely differentiation of neural stem cells is critical during development, and the unrestrained proliferation of neural stem cells in the adult can lead to deadly brain cancers such as glioma. At present our understanding of the key molecules that regulate neural stem cell behaviour during these processes remains limited. In this proposal we will investigate the molecular determinants underpinning neural stem cell biology, both within the developing brain, and within glioma.
Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal coopera ....Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal cooperation paved the way for the origin of parasitism. The second key outcome will be to identify the precise molecular mechanism that allowed parasitism to arise. This will benefit us through understanding the origins of important diseases such as human malaria and related infections of livestock and wildlife.

Symbiotic partnership between algae and animals that powers coral reefs. This project aims to unlock the molecular basis of a partnership between a microscopic plant and an animal that powers coral growth. Most corals depend on microscopic algae living inside their bodies to nourish them. Most corals have to recruit new algae each time they reproduce, but only a particular strain of algae is accepted. This project aims to establish how anemones and corals identify and take in the right alga, how ....Symbiotic partnership between algae and animals that powers coral reefs. This project aims to unlock the molecular basis of a partnership between a microscopic plant and an animal that powers coral growth. Most corals depend on microscopic algae living inside their bodies to nourish them. Most corals have to recruit new algae each time they reproduce, but only a particular strain of algae is accepted. This project aims to establish how anemones and corals identify and take in the right alga, how the alga gives them food, and how the animal hosts regulate growth of their algae to optimise food production but avoid being overrun by algae. Understanding the partnership that drives reef growth and survival may better equip us to protect this threatened resource.Read moreRead less
Biology and evolution of intracellular parasitism. This project will investigate the development of intracellular parasitism in environmental amoebae. The outcomes of this work will help to understand the mechanisms by which bacteria have evolved to survive inside cells and in some cases cause disease.
The Role Of Microglia In Early Diabetic Retinopathy

Funding Amount
$665,582.00
Summary
Diabetic retinopathy is one of the most feared complications of diabetes. This project will examine the role that retinal immune cells called microglia have in causing early changes in the vasculature. We will examine whether diabetes changes the way neurons communicate with blood vessels, opening up a possible treatment target that could prevent the progression to more advanced disease.
Glycosyltransferase Effectors Of Enteropathogenic E. Coli And Salmonella

Funding Amount
$320,891.00
Summary
This project aims to characterise the mechanisms of disease caused by bacterial pathogens including Salmonella and enteropathogenic E. coli. These pathogens cause a significant amount of diarrhoeal disease and mortality worldwide particularly in infants and in countries where water sanitation is poor. I aim to investigate the specific mechanisms the bacteria employ to manipulate and avoid our immune response during infection in order to better understand and combat diarrhoeal disease.
Design And Engineering Of Adnectins For Diagnosis And Therapy

Funding Amount
$803,152.00
Summary
This project aims to engineer a naturally-occurring human protein, called an adnectin, to produce molecules that are able to bind specific targets in the human body, and as such may be used in the diagnosis and therapy of a range of diseases.
